What to do when you're the only one putting in effort in a relationship?

I feel like I'm the only one in my relationship that's putting in effort anymore.

Now more often than ever I'm the one who texts or contacts him first. I go out of my way to make time for him during my day, and he doesn't. I'm the one who takes an hour of transit to visit him, when he has a car. I go to his family gatherings, he bails on invites to mine because he's too busy. But even when I'm busy I make the time to see him. I ask how his day was, but he never asks me back anymore. We've been together 5 months.

Am I wrong for feeling hurt? I make time for people I care about, I just feel like he's not showing that he cares about me, and to be the only one putting in effort makes things difficult.

I'm not sure. You might want to just talk to him. Ask him what's going on and be blunt about it. Here's the thing, if he bails on you because you wanted to talk to him, he's not somebody you want to be with to begin with.
